Gatsby + storybook + async/await + NODE_ENV=production == FAIL

[i8ramin]

Describe the bug

For some reason, the following combination of things causes the Gatsby build to fail:

• async/await code
• @storybook packages
• NODE_ENV=production

Steps to reproduce

Repo with basic Gatsby setup + @storybook devDependencies + async/await code:
https://github.com/i8ramin/gatsby-test-prod-async

git clone https://github.com/i8ramin/gatsby-test-prod-async
cd gatsby-test-prod-async
NODE_ENV=production yarn install --ignore-optional
NODE_ENV=production yarn build

Possibly related GH issues

• ReferenceError: regeneratorRuntime is not defined #5510
• Error with missing regeneratorRuntime #537
• Async/Await #489

Expected behavior
Expect the site to build just fine. Which it does if you do any of the following:

• remove the async/await code, it builds just fine.
• remove the @storybook from devDependencies, it builds just fine.
• add @storybook modules to dependencies, it builds just fine (after issuing rm -rf node_modules && NODE_ENV=production yarn install --ignore-optional)

Screenshots
